A spokesman for the family said Monday that Peter Lanza claimed the remains of Adam Lanza. He says there were private arrangements over the weekend, but won’t elaborate on what those arrangements were.

Police believe Peter Lanza’s home may yield clues into the unthinkable and appalling crime perpetuated by his 20-year-old son — the massacre of 27 people inside Sandy Hook Elementary School and the killing of his own mother inside her nearby home.
